Summary
Roux-en-Y gastric bypass (RYGB) decreases appetite, caloric intake, glycemia, and body weight, all of which are maintained long term.It is controversial whether, after RYGB, patients choose to eat less high fat and sugary foods in favor of lower energy dense alternatives. Therefore the proposition to use direct measures in humans after RYGB to test the hypothesis that the selection and intake of foods varying in fat content and glycemic index, as well as the pattern of ingestion within and across meals, changes in a manner that leads to beneficial outcomes on body weight.
Detailed description
Roux-en-Y gastric bypass (RYGB) decreases appetite, caloric intake, glycemia, and body weight, all of which are maintained long term.It is controversial whether, after RYGB, patients choose to eat less high fat and sugary foods in favor of lower energy dense alternatives. If true, this could conceivably contribute to improved glycemia and body weight. Disparities among studies on food selection and intake are likely due to the almost complete reliance on self-reported food intake which is vulnerable to inaccuracy.This controversy can best be resolved by complementing existing findings with direct measures of target behaviour in humans. Therefore the proposition to use direct measures in humans after RYGB to test the hypothesis that the selection and intake of foods varying in fat content and glycemic index, as well as the pattern of ingestion within and across meals, changes in a manner that leads to beneficial outcomes on body weight.
